You asked:

Evaluate the expression: \(45 - 2.1 \cdot 4.1 + 32\)

MathBot Answer:

\[45 - 2.1 \cdot 4.1 + 32 = \frac{6839}{100} = 68.39\]

\[\begin{aligned}45 - 2.1 \cdot 4.1 + 32& = 45 - \left(2 + \frac{1}{10}\right) \cdot \left(4 + \frac{1}{10}\right) + 32\\& = 45 - \frac{21}{10} \cdot \left(4 + \frac{1}{10}\right) + 32\\& = 45 - \frac{21}{10} \cdot \frac{41}{10} + 32\\& = 45 - \frac{861}{100} + 32\\& = \frac{3639}{100} + 32\\& = \frac{6839}{100}\end{aligned}\]
